The knuckle boom crane is quite like a standard crane with one main difference. The boom is capable of folding back similar to a finger. In essence, the boom articulates at the "knuckle" near the middle. This enables the machinery to be able to transform into a compact size for storage and maneuvering.
Knuckle boom crane arms are somewhat a bit lighter than boom truck cranes. These crane arms are made to enable more payloads to be lifted on the back of the vehicle it is mounted on. Most knuckle boom cranes are mounted behind the cab. This leaves the entire bed of the truck empty.
Smaller models of knuckle boom cranes can be utilized without a certified crane operator, if the load capacity of the machinery is less than 15,000 lbs. or if the boom's maximum length is less than 25 feet long.
Control systems for these cranes are normally different. Some could control from the ground, radio remote control, seated and stand up control. The radio remote systems are capable of running the crane as well as starting it. Furthermore, many models come outfitted with a computer readout system which immediately provides system readouts reporting if the crane is overloaded or not.
Personnel Lifts
Personnel lifts designed by Snorkel have been made to help contractors and maintenance professionals perform tasks at elevated heights. These lifts are portable, inexpensive, lightweight work platforms made for interior use. The patented Girder Lock mast design by Snorkel delivers excellent reach and superb stability. This system, utilized in the UL Series, offers excellent lift capacity.
Snorkel's UL Series Personnel and PAM Series lifts are made so that just one individual is required to operate the machinery. These machinery are easy to transport. They could easily be pushed into position smoothly and pass through a standard sized doorway. These lifts can be erected in minutes and could provide working heights of up to 46 feet, they are an effective alternative to scaffold towers.
